You can bodybuild to your heart's content without steroids, but you can't compete for shit without them. Guys who bodybuild naturally to compete are OK if they are doing it for themselves, but if they start comparing themselves to guys who win contests or the pros, they are being stupid, cause just about every natural show out there has users competing in them.
End of the day, it's all up to you - if you are happy with your looks and the gains you make naturally, great. If you feel you need to juice even if you aren't going to compete, that's fine too - it's your body and your choice. That being said, I do think a lot of people have no idea on how much can be achieved naturally, although it's going to take a lot of time (spanning years) and a whole lot of hard work, and even then, you aren't going to look anything like a pro.
